SAND-PIPE USED ON RAILROAD-LOCOMOTIVES.

Speciflcatiou of Letters Patent.

Patented Nov. 24, 19rd.

Application filed February 4, .1914. Serial No. 816,503.

To all whom it may concern:

Be it known that I, J OHN B. Swing-a citi' zen of the United States, residing at Gladstone, in the county of Delta and State of Michigan, have invented a new and useful Improvement in Sand-Pipes used on Railroad-Locomotives, of which the following is a specification.

This invention relates to improvements in shields for sand pipes for locomotives and other like vehicles.

The object of the invention is ,to provide a sand pipe shield for cutting off the wind and for preventing water produced by condensation of moisture on the rails or from other sources from being blown or otherwise deposited on'the pipe to which this shield is applied and forming ice at the bottom of said pipe,thereby avoiding choking of the pipe. l I Another object is to provide a dev ce of this character which concentrates the flow of sand on the rail and more especially at curves.

1th the above ob ects in view, the invenstruction, combination and arrangement of parts as will be more fully described and claimed.

In the accompanying drawings: Figure 1 1 represents a side elevation of thisimprove-d guard or shield applied; Fig. 2 1s a front elevation thereof; Fig. 3 1s a perspective view on areduced scale of this improved shield taken from the bottom; Fig. 4 is a perspective view with the pipe shown in dotted lines; Fig.6 is a detail plan view of the securing clamp shown closed in full lines and open in dotted lines; Fig. 6 is adetail perspective of the gasket; Fig. 7 1s a perspective view of the guard with the parts separate and arranged in juxtaposition ready for assembling.

In the embodiment illustrated, a sand pipe P is shown of ordinary construction and to which is applied this improved guard 1. This guard 1 comprises an outer skirt 2 and an inner skirt 3 flared at their tops for a portion of their length and each split longiskirt when applied, extends several inches below the lower end of the sand pipe P. Disposed within the skirt 2 is the inner skirt 3 slit throughout its length and its edges tapering toward its top from a. point corresponding to a point at which the tapermg begins on the outer skirt 2. This skirt 3 fits snugly within the skirt 2 at it's top and conforms somewhat in shape thereto. The straight edges of the inner skirt 3 have outturned lips i which overlap'the straight edges of the outer skirt 2 as shown in Fig. -l and holds-aid skirts against lateral movement relatively to each other. The-lower portion of the inner skirt 3 opposite its slit side is bent to form a funnel like member 5 for concentrating and directing the sand onto the track. The slit upper ends of the skirts 2 and 3, are closed by a transversely carved plate 6. the edges of which taper to ward its upper end to adapt it to conform to the shape of the skirts 2 and 3. This closing plate 6 spans and closes the slit portions of the skirts and 3 throughout their tapered portion leaving thepart below open. tion consists of certain novel features of concuring screw or bolt'is adapted to pass for securing it in operative position on the pipe,

said clamp being adapted to encircle the up per ends of the skirts over the gasket and thereb; securely fasten the guard tothe p n In the use of this invention. when the skirts are clamped to the pipe P as above described, the lower edges thereof project several inches bclmwthe lower end of the pipe and the funnel shaped member of the inner skirt is positioned to direct the sand from thepipe and to concentrate it on the t ack over which the pipe is disposed, the flared lower end of the skirts protecting said pipe end from water. of condensation or otherwise. such as is usuallv thrown against the pipe and combines with the san d,'ver v often clogging and entireiv stopping the opening in the-pipe.

l: elaiin as my invention:

1. A sand pipe protector comprising inner anel outer skirts flaring throughout their length toward their bottoms and one of them hoving means at one side thereof for concenhating the flow of sand on the rail and means for securing said shirts to a sand pipe.

2. A send pipe proiector comprising inner and outer skirts flaring toward their bottoms, the inner skirt having means at one side thereof for concentrating and direr ting iii-e flow of san l onto the rail, and means for sceurin said shirts to a sand pipe.

3. A semi ipe protector comprising inner and outer sxirts, the inner skirt having a funnel-shaped elemen h at one side for coneenirating and; directing the flow of sand onto the rail, and means for securing said skirt to a sand pipe.

4%. A sand pipe'pro'tector comprising two flared longitudinally split skirts arranged one within the olher with the openings reg istering with each other, and a closure for the upper end ofsaicl split portions.

5. ll sand pipe protector comprising two flared longitudinally split skirts arranged one within the other With. the openings registering with each other, and a tapered plate overlapping the upper end of the split portions of said skirts.

6 A sand pipe protector comprising inner and outer skirts arranged one within the other and split longitudinally throughout their length, the inner skirt having outwardly extending backturned lips along the edges oi the split portion thereof to receive the split edges of the outer skirt, whereby said skirts are held against lateral 1novement relatively to each other.
